Pluto is one of many ice dwarves in the outer Sol system. It is primarily composed of rock and ice. Due to the remoteness of Pluto, it has not been significantly exploited by any faction.

Pluto was long believed to have been a planet, but with the discovery of other ice dwarves in the system, this is no longer the case. Modern navigational systems classify Pluto as a planet for organizational purposes.

Pluto has a highly eccentric orbit due to its extreme axial tilt. This causes it to occasionally cross orbits with Neptune. Pluto itself is composed of at least 98% nitrogen ice with traces of methane and carbon monoxide. Its large moon, Charon, is also made of ice though contains more methane and carbon monoxide ice instead.

Pluto has a thin atmosphere of nitrogen, methane and carbon monoxide, making it warmer than usual for a celestial body its distance.

Pluto has numerous moons. Charon is its largest, only slightly smaller than Pluto itself, and it has four tiny moons of its own which are barely observable from Gaea. Charon is big enough to be considered binary to Pluto.
